i have had a pair i built up a few years ago. they're on my main ride and still in full use with no problems. had to replace the bearings once (sealed) but that's to be expected

i really like the piece they have to hold tension on the bearings, much nicer that older counter-tighten method. i also really like the allen bolts. it's a lot nicer to just carry a little allen set (which i do anyway) to get the wheels on and off instead of a 15mm wrench.
